Definition of net national product in English:

noun

When a country depletes its natural capital, this is typically ignored in the national accounts, even though depreciation of man-made capital is allowed for (to convert from GNP to net national product, NNP).

As a proportion of net national product, central government expenditure in Britain fell from around 18 per cent in 1820-4 to 8.2 per cent in 1910-13; the comparable figures for Germany are 20 per cent and 6.6 per cent.

Hobson calculates that the British ‘military burden’ between 1870 and 1913 averaged a mere 3.2 percent of net national product; by contrast, the figure for the United States between 1950 and 1974 was 9 percent - nearly three times higher.
